Anyone running a Rev 4 on Mercury 250 XS Pro?

[Tim Ellis]

I am wondering if anyone is familiar with the performance of a Rev 4 prop 21 pitch on a 250 XS Pro. I would appreciate any feedback or what i could expect running this prop on this motor? Presently have a Tempest Plus. Boat is a 2008 Ranger 621.

The Rev 4 will perform awesome on the 621, depending on what rpm your running with the tempest 21. Post your rpms and speed then we can figure out your prop slip that you have now, that will tell me if you can gain any mph switching to a 4 blade.

With a light load at 5500 to 5600 rpm i can hit 59-60 mph.

I had a tempest on mine, it was quick, but was horrible in anything over 2ft chop. KGONE and others told me to get the REV4. I did, it is a new boat now. I was ready to put it up for sale it rode so rough. Very happy! Im broke now, but happy!!!

[K Gonefishin]

I seriously don't know how guys even run a 3 blades, when I got my new boat I thought something was wrong with the hull, it rode aweful. I guess most guys are just concerned about that top end, the tempest offered the highest mph but that's it. It's uselss otherwise. I guess if I fished inland puddles it would be okay but even then they get some chop to them. :smokin:

I've been told by many that the REV 4 is a hard wheel to turn. Knowing this, what kind of speed difference are you guys that have ran a tempest noticed? Also, what kind of pitch change is needed to equal the RPMs that you'd turn with a tempest. I've talked about trying one for a long time but just haven't made the jump yet. Currently I have a 21P Tempest Plus and a 22P High Five. These are the two I've settled on for now. I've also tried a few others including a 22P Enertia, 21P Vengance, & a 23P Trophy, none which I liked much!

With the 21p Rev-4 I ran 150 RPM less than the 21P Tempest. That was around 1.5MPH at WOT. (2007 Ranger 620, 225 ProXS, with full load)
I do notice a little more 'torque' on the wheel with the Rev-4 and the boat is much more trim sensitive.

[K Gonefishin]

You are right I guess the Rev 4 is a hard prop to turn I've been told that by my dealer and others it's not for everyone. I turned 5300-5400 at 55-57 MPH with a full load running a 23 Tempest. I now turn just shy of 5900 with a 21 Rev 4 around 52-55 MPH depending on load. I have yet to really crack it open with one person low on gas to see what my full top speed would be with just myself in the boat, always alot of butt and fuel in the boat and full tourney load. These are my normal running conditionss and I normally see 53-54mph with 3 big guys full tank at 5850 or so give or take a few RPM's. I talked to another guy same motor and boat and he sees 57 it's defintely due to less butt in the boat me and my fishing partner weigh the boat down this I know, we're all big fella's.

I ran a 23 high 5 and I was seeing 53-55 mph, tons of lift and control and great in big water but a little overkill for my liking bow was too high I also was bumping my rev limiter with ease with this prop RPM's to high. Good prop though.

Thanks for the quick response guys! One more question and I'll quit hijacking the thread,. What do you mean by more trim sensitve? I only ask as I notice when loaded full of fuel and whith a few big guys in my yarcraft I have a hard time bringing the nose down unless running up towards 30mph and this can create a rough ride if the nose is up a bit. I was even tempted to try a cobra foil to get some sterm lift a slower speeds but I keep thinking eventually I'll find a prop thats a happy medium, it almost sounds from the way you guys talk that the REV 4 could be that prop. one thing I like about the tempest is the big blades really stay hooked up weather running in rough water with the nose up at slow speed or when flat out hauling across the water I can trim to my trim stop without it even thinking about blowing out. This was what I didn't like about the Enertia, the small blade diamter cause me to blow out much easier and I didn't have near the adjustment when trimming out.

I experienced the opposite I couldn't keep the tempest buckled up going into 2,3,4's on Erie, it was blowing out on me...no bite whatsoever. The Rev 4 stays hooked up no matter what. Bites like a pit bull. I'm mounted on the second highest hole from the top FYI, If the motor was mounted 2 more down it would probably be a little better but who knows I didn't play with motor height with the tempest

Was this when running flat to the water or with the bow in the air and the motor trimmed out? Out of the five props I've tried the tempest has had the best bite with the high five a close second, the rest weren't even a comparison. The only thing I can think of is the waves on Erie are probably spaced quite a bit further apart than what I encounter on Sakakawea and of course the obvious difference in the boat we are each pushing.

[K Gonefishin]

No trim at all motor tucked all the way in bow up trying to get through rough water with a good ride without pounding. I have a 621 what are you running.

[Modog]

By 'trim sensitive' I mean that with the Rev-4 the hull responds quicker and you can feel the change better when you bump the trim either out or under. I agree with Kgone, the Rev-4 stays hooked up in rough water.
It's tons better in reverse than the High-5 too.

[SLE]

[Thanks guys, there's no doubt the High-5 isn't real good for backing up! Kgone my boat is an 1895 Yar-Craft Storm and I'm running an 05' 225 Optimax. One difference from a lot of boats is the way my transom is designed. The Yar-craft has a "Sump" type cut out at the center rear keel line which houses the intakes for the livewells and the drain plug. The sump is back about 8" from the main trasom. My self and a few other Storm owners have noticed that you can virtually raise you motor all the way up using a jack plate and you don't hardly lose water pressure. We attributed this to the cutout in the transom. This could also play a role in why myself and a couple of other storm owners all ended up with the Tempest Plus and have found it offered great bite on our boats.

If you look at the picture (If the picture actually works, lol), look infront of the motor at the keel line of the transom and you will see the "sump" that I'm talking about.

I'm gonna have to look back in the archives, I think somebody else running the same boat had tried a REV 4. I'll post back if I find what the results were.

I have a 215 Triton and run a rev4 on it...boat came with a tempest and I ran that prop 1 time on erie before it came off for the same reason Kgone described......B-lou

With a light load at 5500 to 5600 rpm i can hit 59-60 mph.

That motor calls for 5500 to 6000 rpm, so your on the lower end of that range, So if you what to go with a REV4 your going to lose 200 rpms if you go with a 21 pitch, if you went to a 19 pitch you gain some rpms but you'll really lose your speed. I would have your motor raised so you can gain some rpms with a 21 pitch REV4. As far a speed loss you will lose 2 mphs or so. But you'll have alot better ride and better performing boat.
